Introduction

What is engineering? What is an engineer?? Although it is a very old activity or trade, engineering is arelatively young academic discipline or profession. Only in recent years has it reached a stage of maturity where some of its definingdetails and differentiating characteristics can be articulated. Engineering is the endeavor that creates, maintains, develops, andapplies technology for societies' needs and desires. Its origins go back to the very beginning of human civilization where tools werefirst created and developed. Indeed, a good case can be made for the defining of humans as those animals that create, develop, andunderstand the significance of technology.

Over time, the part of technology that acts as an extension of human capabilities became the purview ofengineering. One can view bicycles, cars, and trains as extensions of walking and running. Airplanes are an extension and applicationof a bird's ability to fly transferred to humans. The telegraph, telephone, radio, television, and the internet are extensions oftalking, hearing, and seeing. The microscope, telescope, and medical x-ray are also extensions of human sight and vision.Writing, books, libraries and computer data-bases are extensions of human memory and the computer itself is an extension of the human'sbrain in doing arithmetic and carrying out logical arguments and procedures. Indeed, looking around your environment in almost anysetting, will illustrate just how pervasive technology is. In almost any home or office, there is very little that is truly"natural"; i.e., little that is not created or manipulated by technology. The food that you eat, the utensils that you eat with,the table that you eat off of, the house that you are in, the clothes that you wear, the book that you read, the television thatyou watch, the telephone that you communicate with, the car that you travel in -- these are all technologies created by humancleverness to satisfy human needs. This process of creation is engineering and those who do the creating are practicingengineering, whether they call themselves engineers or not.

Not only is much of the inanimate world created by engineering, part of the living world is also. Almostall crops and agriculturally produced food stuff are "engineered" through selective breeding. The same is true of domestic animalssuch as pets and animals raised for food or sport. Certainly the dogs, cats, and cattle have not "naturally" evolved to theircurrent state. They have been “created” or “designed” to satisfy human desires or needs. The slow and less exact methods ofcontrolled breeding are being replaced by genetic engineering, tissue engineering, and applications of nanotechnology. We humanshave the cleverness to do that. It is the development of the tools, theories, and methods and the understanding of the appropriatesciences and mathematics for that process that is engineering. It is a central part of the history of humanity.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
